Recurrent pulmonary hydatid disease: Analysis of ten cases

Purpose  To investigate the incidence and define the importance of recurrent pulmonary hydatid cysts in developing countries. Methods  We analyzed the records of 312 patients with pulmonary hydatid cyst disease diagnosed in our center between 1999 and 2005. Results  A recurrent pulmonary hydatid cyst was diagnosed in 10 (3.2%) of the 312 patients [8 men and 2 women, mean age 36.9 (range 20–60) years]. The diagnosis was based on radiographic, clinical, or serological findings, established intraoperatively. The most frequent symptom of recurrent pulmonary hydatid cyst was hemoptysis (60%). The mean interval between diagnosis of the initial hydatid cyst and detection of recurrence was 8.75 (range 3–15) years. Bronchoscopy was performed in all patients, but proved diagnostic in only one. The localization of the initial and recurrent cysts differed in seven patients. A median follow-up period of 5 years revealed second recurrences in only two patients; manifesting as an intrapleural rupture of the cyst in one and as empyema in one. The recurrence was treated by resection in all patients; as cystectomy in eight patients, lobectomy in one patient, and pneumonectomy in one patient. Conclusion  Pulmonary hydatid cyst may recur in the same or a different location in the lung. Patients with a pleural lesion must be followed up regularly for any signs of recurrence.     

Surgical Treatment for Lung Hydatid Disease

Lung is the second most common site for hydatid disease after the liver. The aim of this study is to present the clinical symptomatology, diagnostic evaluation, and surgical techniques for the treatment of lung hydatid disease. During the last 25 years, 42 patients with lung hydatid cysts were treated surgically in our department. In four patients there were cysts in the liver and in one case in the spleen. The cysts were located in the right lung in 16 patients (38%), in the left lung in 23 patients (54.8%), and in both lungs in 3 patients (7.14%). Eighteen patients (42.9%) presented with complications: suppuration in one patient (2.4%), rupture to the bronchial tree in 16 patients (38%), and pneumothorax in one patient (2.4%). Diagnosis was established preoperatively in all cases; chest radiography and computed tomography were most helpful for diagnosis. Forty-six operations were performed in 42 patients; three patients with bilateral cysts underwent staged thoracotomies, and one patient was reoperated for recurrent disease. All cases were managed surgically, with several types of radical (34 cases) or conservative (12 cases) procedures. Radical procedures were lobectomy and rarely pneumonectomy, which were used more often during the first half of the study period. Cystectomy with capitonnage, the most commonly performed conservative procedure, was mainly used during the second half of the study period. Postoperative morbidity was 15.2% and the 30-day mortality rate was 0%. In one case there was postoperative hemorrhage that required reexploration. The median hospital stay for uncomplicated cases was 12 days and for complicated cases 21 days. In conclusion, pulmonary hydatidosis often presents with complications requiring emergency surgery. A lung-conserving operation is the treatment of choice for lung hydatid disease and offers a good surgical outcome with a minimal recurrence rate.     

Comparison of pulmonary hydatid cysts in children and adults

BACKGROUND: The purpose of the present study was to compare the clinical features and the surgical approaches of the pulmonary hydatid cysts in children and adults. METHODS: One hundred and thirty-four patients, operated on for pulmonary hydatid cysts over the last 10 years were retrospectively evaluated in two groups: 39 children who were younger than 18 years old (29%) and 95 adults (71%). The patients in each group were analysed according to their clinical, radiological and surgical findings. RESULTS: The frequency of pulmonary hydatid cysts in children was significantly higher in boys (74%) than in girls (26%). However, there was no sex tendency in adults (52% in male vs 48% in women). The sex difference in hydatid cyst frequencies between adults and children was significant (P < 0.05). Among preoperative pleural complications, pneumothorax (15.5%) in children and empyema (11%) in adults were more frequent. The frequency of concomitant hepatic cysts was less in children than in adults (33%vs 79%). Huge pulmonary cysts (=10 cm) were more common in children (31%) than in adults (22%). Cystotomy with capitonnage was the most frequently preferred method in both groups. Postoperative complications developed in six children (16%) and 19 adults (19%), and were more frequent in patients with huge cysts (27%vs 16%). No recurrence was observed in both groups. CONCLUSIONS: Isolated pulmonary cysts are more common in children than adults. The cysts also tend to be bigger in children than adults. The frequency of concomitant hepatic cysts is less in children. Because of higher lung expansion ability and improvement capacity in children, resection should be avoided and lung saving surgical procedures should be performed. In spite of differences observed in the clinical features it does not change the treatment of pulmonary hydatid cysts in children.     

One-stage Transthoracic Operation for the Treatment of Right Lung and Liver Hydatid Cysts

In this study we reviewed our experience of hydatid disease of the lung and the liver and discussed the safety and the follow-up results of the one-stage operation. Between 1990 and 2004, 142 patients with pulmonary hydatid disease underwent operation in our clinic. Of these, 27 (19%) patients had cysts located on the dome of the liver, treated with phrenotomy through a right thoracotomy. Hydatid cysts located in the lungs were managed by means of cystotomy. For liver cysts, cystotomy and the inversion of the cavity with sutures was the surgical method of choice, and a drain was left in place. The pulmonary cysts of 12 (8.4%) patients were bilateral and 5 (3.5%) patients had prior surgical treatment of hepatic (n = 1) or pulmonary (n = 4) hydatid cysts. The liver cysts were approached transdiaphragmatically after the lung cysts were excised in 27 (19%) patients. In patients with pulmonary cysts, cystotomy, with or without capitonnage was performed on 123 (86.6%) patients, and wedge resection was performed on 11 (7.7%), segmentectomy was performed on 6 patients (4.2%), and lobectomy was performed on 2 (1.4%) patients. There was no mortality, and only a small number of complications were encountered: empyema in 3, excessive biliary drainage in 2, and bronchopleural fistula in only 1. We suggest that the extraction of pulmonary and hepatic cysts simultaneously through the transthoracic route is a useful and safe surgical technique. This technique also prevents the need for a second operation.     

Hydatid cysts of the lung: lesion size in relation to clinical presentation and therapeutic approach

Purposes

The aim of this study was to assess the relationship between the pulmonary hydatid cyst size and the clinical presentation, surgical approach, and postoperative outcome. We review the problems encountered in treating large pulmonary hydatid cysts and highlight the risks associated with the rupture of the cyst and a delay of the surgical treatment.

Methods

The medical records of 169 patients surgically treated for lung hydatid cysts were reviewed. Patients were divided into two groups based on cyst size: group 1 (n = 128) with small (<10 cm) cysts and group 2 (n = 41) with giant (≥10 cm) cysts. Data related to symptoms, preoperative complications, surgical procedures performed and postoperative morbidity were analyzed and compared.

Results

In both groups, the most common symptom was chest pain, followed by dyspnea and cough, respectively. There were no differences between the two groups with respect to cyst-associated parenchymal or pleural complications before surgery (p = 0.80). In the large majority of cases, the surgical treatment was cystotomy, removal of the cystic membrane and capitonnage. Wedge resection was performed in nine patients in total (seven in group 1, two in group 2) and one patient in group 2 required a lobectomy. Decortication was required significantly more frequently in group 2 than in group 1 (p = 0.001). Sixteen patients in group 1 and 10 patients in group 2 developed postoperative complications (p = 0.19). There was no peri or postoperative mortality. There was no difference between the groups with respect to the duration of hospitalization (p = 0.17). Two patients with complicated hydatid cysts in group 1 had recurrent lesions during follow-up, whereas there was no recurrence in group 2.

Conclusion

All pulmonary hydatid cysts should be surgically treated as soon as possible after their diagnosis in order to avoid complications. Most of these lesions, regardless of size, can be surgically managed with procedures that preserve the maximal lung parenchyma and yield excellent outcomes.     

Surgical Treatment of Mediastinal Cysts: Report on 29 Cases

Aim : Mediastinal cysts are rare, forming 12–18% of all primary mediastinal tumors. The purpose of this study is to evaluate type, clinical properties, treatment modalities, and results of mediastinal cystic neoplasm in the light of available literature.

Patients and methods : We retrospectively investigated 29 patients who were diagnosed and surgically treated for mediastinal cysts in our clinic between January 1996 and May 2011.

Results : Sixteen (55.2%) patients were male and 13 (44.8%) were female. The average age of the patients was 36.5 ± 22.1 (17–77 years old). The mediastinal cysts comprised 11 (37.9%) bronchogenic cysts; seven (24.1%) hydatid cysts; four (13.8%) benign cystic teratomas; three (10.3%) pericardial cysts; one (5.3%) thymic cyst; one (5.3%) cyst of the thoracic duct; one (5.3%) enteric cyst; and one (5.3%) lymphangioma. Approach methods were thoracotomy in 18 (62.1%) cases; video-assisted thoracoscopicsurgery (VATS) in seven (24.1%) cases; median sternotomy in three (10.3%) cases; and anterior mediastinotomy in one case. Postoperative observations during the follow-up period showed chylothorax in one patient; pleural effusion in one patient; and the recurrence of a bronchogenic cyst in one patient five years after the operation. Postoperative mortality did not occur in any case. The average postoperative hospitalization period was 7.3 days (2–14 days).

Conclusion : A surgical approach to mediastinal cysts offers histological analysis, pathological diagnosis, curative treatment, and prevention from complications.     

One stage bilateral thoracotomy for hydatid cysts of both lungs

Background Though pulmonary hydatids are quite frequent in India, bilateral pulmonary hydatids are rare. Generally two stage posterolateral thoracotomy is done for surgical resection of bilateral hydatids. Our objective was to study the safety of one stage bilateral small thoracotomies for managing bilateral pulmonary hydatids. Methods From 1996 through 2003, 216 pulmonary hydatid cysts were managed surgically. Out of 18 cases of bilateral cysts, 12 cases were managed with one stage bilateral thoractomy. One stage anterolateral mini thoracotomies with 30° tilt were done on both sides, one after another. Hydatid cysts were removed, bronchial leaks were sutured and dead spaces were obliterated. In two patients, segmentectomy & in one patients lobectomy was done due to destroyed lung parenchyma. Chest was closed with water seal drains. Post operative albendazole was continued for 3 months in the dose of 10–20 mg/kg with a gap of 2 weeks after each month. Post operative recovery was uneventful in most of the cases. Results Out of 216 patients of hydatid lung, 12 (5.55%) were managed surgically with one stage bilateral thoracotomy. Mean age was 24.3 years (youngest 9 years and oldest 72 years). Male: female ratio was 7: 5. Mean operating time was 90 mints. (Range 70 mints. to 130 mints). Average blood loss in chest drain was 300 ml. There was no mortality and no major complications Air leak continued for 3 weeks in 2 patients. Till date there is no recurrence. Conclusion One stage bilateral mini thoractomy is a suitable & safe option for surgical management of bilateral pulmonary hydatids.     

Single-stage transthoracic approach for right lung and liver hydatid disease

OBJECTIVE: Human echinococcosis remains a serious health problem for the Mediterranean countries. Synchronous pulmonary and hepatic hydatid disease may occur in 4% to 25% of cases. Our experience on simultaneous surgical treatment of right lung and liver hydatid disease in patients was reviewed. METHODS: Between 1990 and 2000, 48 patients (33 female patients and 15 male patients) with synchronous right lung and liver dome hydatid cysts were operated with a 1-stage procedure. RESULTS: Six patients had previous surgical treatment of hepatic (n = 2) or pulmonary (n = 4) hydatid cyst. The pulmonary cysts were diagnosed with radiography in 18 patients and thoracic computed tomography scan in 30. The pulmonary cysts of 9 patients were bilateral. Seventy-five pulmonary cysts were seen in radiological examinations. The diagnosis of hepatic cysts was established with ultrasonography in 18 patients and upper abdominal computed tomography in 30. The total number of hepatic cysts was 48. In cases with pulmonary cysts, cystotomy and capitonnage were performed in 32 patients, only cystotomy was done in 14 patients, and wedge resection was performed in 2. Liver cysts were approached to transdiaphragmatically after the lung cysts had been dealt with and were managed with evacuation of the cysts. In the remaining cases, marsupialization (n = 2), pericystectomy (n = 1), and enucleation (n = 1) were performed. Major postoperative complications were hemorrhage (n = 1) and biliocutaneous fistula (n = 1). Hepatic recurrence was seen in 3 patients (6.2%) and pulmonary recurrence in 1 (2.1%). CONCLUSION: Transthoracic approach is a useful and a safe surgical management of both pulmonary and upper surface of hepatic hydatid cysts.     

Changes in surgical therapy of pulmonary hydatid cysts

The lung is the second most common site of hydatid cysts after the liver. The authors analyse retrospectively the results of patients treated with pulmonary hydatid cysts in the past 18 years, considering video-thoracoscopy. Twenty eight patients were treated during this period in 31 cases. Hydatid disease affected only the lung in case of 22 patients, while in 6 cases it was present in the liver and lung simultaneously. Pulmonary hydatid disease affected one side in 24 and both sides in 4 cases. For surgical treatment pericystectomy in one, atypical segment resection in 18, anatomical segmentectomy in three, lobectomy in 7 and video-thoracoscopy in 3 cases were performed without surgical complications. The mean hospital stay was 10.5 days in case of thoracotomies and 8.5 days in case of video-thoracoscopy. There was one recurrence in conventional surgery and reoperation was necessary. After video-thoracoscopy no recurrence was detected. Mean follow-up was 120 months, after video-thoracoscopy it was 20 months. Three patients have uncertain chest pain after thoracotomy, but none has any complaints after video-thoracoscopy. Fifteen patients took mebendazole permanently after the final histological result. According to the authors' practice the indication of lung resections for pulmonary hydatid cysts is limited, in selective cases video-thoracoscopic cystectomy can be a successful treatment of choice.     

Surgical treatment of pulmonary hydatid cysts in children

PURPOSE: Ten years' experience is analyzed in pediatric patients with pulmonary hydatid cysts. METHODS: Between 1990 and 2000, 33 pediatric patients (2 to 15 years of age) with pulmonary hydatid cysts were operated on in Department of Thoracic Surgery in Ankara University School of Medicine. There were 17 girls and 16 boys. RESULTS: Twenty-three cases presented as a solitary lung cyst, whereas the remaining 10 were found to have multiple cysts in one or both lungs. Cystotomy and capitonnage were performed in 25 patients, cystotomy was done in 6 patients, and only 2 patients underwent the wedge resection. The authors used no scoliocidal agent in our approach. There was no operative mortality. Recurrence after operation was seen in one patient. CONCLUSION: Pulmonary hydatid cysts in children can be treated successfully by cystotomy and capitonnage or only cystotomy. J Pediatr Surg 36:917-920.     

Bilateral lung and liver hydatid cysts. Case report

Introduction. Synchronous occurrence of pulmonary and hepatic hydatid cysts is an uncommon manifestation of hydatid disease that is observed in less than 10% of cases. We report a rare case of bilateral lung (with bronchial fistula) and liver cyst, surgically treated after medical therapy. Case report. A 44-year-old housewife reporting fever, anorexia and fatigue that had been present for the previous 20 days received diagnosis of bilateral lung and liver hydatid cyst. Because of the dimensions of right lung cyst and the successive bronchial fistolization, we proceeded to three-stage operation of two thoracotomies and a laparotomy to control the risk of further rupture. After surgery, all post-operatives were uneventful. Complete resolution of the therapy with no evidence of recurrence at 2 years follow-up. Conclusion. We emphasize the need to search for additional hydatids in patients who present with either pulmonary or liver hydatids. The simultaneous treatment of liver and lung should be reserved to patients in good conditions; in all other cases, especially when one cyst is more symptomatic than the others or has more risk of rupture, we prefer to treat single cyst.     

Conservative Surgery for Treatment of Hydatid Cysts in Children

Human echinococcosis is endemic in Turkey and many other areas of the world. Fifteen years of surgical assessment related to involved structures, operative procedures, complications, and the recurrence rate is analyzed in pediatric patients with pulmonary and abdominal hydatid cysts. Between 1986 and 2001, the records of 42 pediatric patients (15 girls, 27 boys; ages 2–15 years) with pulmonary and abdominal hydatid cysts operated on in our clinic were analyzed retrospectively. The features of the disease, involved structures, operative procedures, complications, and recurrences were noted. A total of 26 patients presented with solitary cysts in the lung (9) and liver (17). Another 11 had multiple cysts in both lung and liver, and 5 had disseminated abdominal disease. Conservative surgical procedures were used for all lung and liver cysts: cystotomy (7) or cystotomy plus capitonnage (13) for lung cysts; partial pericystectomy with capitonnage (25), omentoplasty (28), tube drainage in the presence of bile leakage (5), or a combination of these procedures for liver cysts. Cyst excision was used for omental and peritoneal localizations when feasible. Radical procedures were never used (wedge or major liver and lung resections). Operative mortality was zero, and the morbidity rate was 14%. Three patients with disseminated disease (7%) showed recurrence. We suggest that no partial organ resections are necessary for hydatid disease, and highly successful results can be achieved using conservative surgical approaches, such as cystotomy plus capitonnage for lung cysts and partial pericystectomy with capitonnage, omentoplasty, or both for liver cysts.     

Management of pulmonary hydatid cysts in a tertiary care centre in Northeast India

Background

Hydatid cysts are the most common parasitic disease of the lungs. We reviewed our experience with pulmonary hydatid cysts focusing on clinical symptoms, diagnostic methodology, operative management and their outcome in our centre.

Methods

Between October 2008 and September 2013, 37 patients were operated in our department for lung parenchymal hydatid cysts. Twenty-six patients were female and 11 were male. The mean age of the patients was 30.6 years with a range of 16–44 years. The cysts were located in the right lung in 22 (59.46 %) patients, left lung in 14 (37.84 %) and bilaterally in 1 (2.70 %). We performed enucleation and capitonnage in 29 cases, cystotomy-drainage and capitonnage in 6 cases, wedge resection in 1 case and lobectomy in 1 case. Albendazole was given postoperatively to selected patients considered to be at high risk for recurrence.

Results

Chest X-ray, computerized tomographic scanning of the thorax was done in all cases for diagnosis. Most of the patients presented with solitary pulmonary cysts. One patient had bilateral pulmonary cysts and four patients had concomitant liver cysts. Postoperatively, there was no major morbidity. There was no in-hospital or 30-day mortality. The follow-up data was complete for 29 of the 37 patients. The mean follow-up period was 2.6 years with a range of 6 months to 5 years. During the said period, none of the patients had shown any recurrence.

Conclusion

Surgery for hydatid cysts of the lung can be safely performed, with low morbidity and a negligible mortality rate and is the treatment of choice.     

Pulmonary hydatidosis: surgical treatment and follow-up of 240 cases

Objective: We review a series of 240 patients treated surgically for pulmonary hydatid cyst in our center between 1966 and 1988, assessing the results with our surgical technique, which involves a novel needle aspiration device designed by Professor D. Figuera, and postoperative treatment protocol. Patients and methods: The majority (60.4%) of the patients were from areas endemic for hydatid disease. The mean age of the patients at the time of the surgical procedure was 31.5±7.2 years (range: 4–70 years). A trocar-suction device was used for the needle aspiration of 276 (92%) of the 300 cysts encountered in the 240 patients. The remaining 24 cysts were removed integrally by means of different surgical techniques such as cyst enucleation, lobectomy, segmentectomy and atypical pulmonary resection. The residual cavity was treated by pericystectomy and eversion to the pleural surface in 238 cases (86.2%) and by capitonnage in 38 (13.7%). High vacuum suction (−30 cm H₂O) was employed in every case. Depending on when the procedure was performed, the patients were treated with mebendazole or albendazole according to the protocol designed by Bekhti. Results: Clinical assessment of the symptoms and plain chest X-ray led to the correct diagnosis in 228 cases (95%). In six (2.5%), imaging studies such as ultrasonography, computed tomography and nuclear magnetic resonance were required, and in the remaining six cases (2.5%), the diagnosis was established intraoperatively or in the subsequent histopathological study. One hundred and seventy patients (70.8%) presented a solitary lung cyst, while the remaining 70 (29.2%) were found to have multiple cysts in one or more lobes of one or both lungs. In addition, 45 patients (18.7%) presented hepatic cysts and 25 (10.4%) had cysts in other locations. After 18 years of follow-up, the survival rate was 94.6%. Of the surviving patients, 98.3% were free of pulmonary hydatid disease and 95.1% were free of hydatid disease. Conclusions: The trocar-suction device employed here for needle aspiration of hydatid cysts has demonstrated its efficacy in preventing the rupture of the cyst and its possible dissemination. With its use, the parasite is eradicated and the residual cavity can be excised.     

Conservative Surgical Treatment of Pulmonary Hydatid Disease in Children: An Analysis of 35 Cases

Purpose. Hydatid cyst disease is a major health problem for people who live in endemic countries such as Turkey. The definitive cure for pulmonary hydatidosis is still surgical. This study evaluates our experience of treating pulmonary hydatidosis, focusing on the conservative surgical management of children with this disease. Methods. We retrospectively analyzed 35 children ranging in age from 3 to 13 years old, treated for pulmonary hydatidosis during a recent 4-year period. Results. The 35 patients had a collective total of 48 cysts. Twenty-seven patients had a single cyst, 7 had unilateral multiple cysts, and 1 had bilateral multiple cysts. Six patients had multiple coexisting liver cysts. The 33 pulmonary cysts were intact and uncomplicated. Of the total 48 cysts, 34 were larger than 5 cm in diameter. Fever, cough, and dyspnea were the most common symptoms and chest radiography gave a correct diagnosis in 96.4% of the patients. Conservative surgical treatment was carried out in 33 of the 35 children (94%). There were few postoperative complications, and no mortality or recurrence in this series. Conclusions. Parenchyma-saving surgical procedures such as cystotomy and capitonnage are the preferred methods of treatment for pulmonary hydatid disease in childhood. These simple procedures are safe, reliable, and successful. Combined medical treatment can be given but not as an alternative to surgery. Simultaneous surgical procedures for coexisting liver cysts may be preferred because of the lower morbidity rates and hospitalization. Ultrasound or computed tomography scanning should be done to detect coexisting liver cysts in every patient with pulmonary hydatid disease.

Surgical treatment of hydatid cysts of the lung: analysis of 405 patients

Objective

The choice of operation, postoperative success and complications of surgery in patients with pulmonary hydatid cysts.

Design

A series of patients seen over 15 years.

Setting

A university clinic.

Patients

Four hundred and five patients (209 male, 196 female) ranging in age from 4 to 72 years (mean 29 years). Most (367 patients) had isolated lung cysts; 38 had both liver and lung cysts.

Interventions

A variety of procedures to remove cysts, including enucleation and capitonnage, wedge resection, segmentectomy, lobectomy and pneumonectomy. Six patients with bilateral cysts were operated on through a median sternotomy approach. Others underwent posterolateral thoracotomy.

Main outcome measures

Value of diagnostic tests, the most efficacious approach for cyst removal and recurrence and death rates.

Results

Chest radiography gave a correct diagnosis in 99% of patients. The Casoni and Weinberg tests were discontinued because of high false-negative rates (up to 35%). Hospital mortality was 1.2% and postoperative complications occurred in 5.2%. The recurrence rate was 1.5%.

Conclusions

Lung-preserving surgical interventions are the treatment of choice for pulmonary hydatid disease. In patients with bilateral cysts, the median sternotomy approach is preferred, and in the patients with right lung disease and coexisting liver cysts the transdiaphragmatic approach is the one of choice to remove cysts in 1 stage.     

Long-term surgical outcome in patients with intracranial hydatid cyst

Summary Background. Cerebral hydatid cysts account for up to 3.6% of all intracranial space-occupying lesions, in endemic countries. The vast majority of patients affected are children. Computed tomography (CT) and magnetic resonance imaging (MRI) have greatly contributed to a more accurate diagnosis of hydatids. However, correct pre-operative diagnosis still remains quite puzzling. Extirpation of the intact cyst is the treatment of choice, resulting in most cases to a complete recovery. Method. In our retrospective study, we have reviewed 76 cases of intra-cranial hydatid disease operated on in our hospital over a 22 year period. Presenting clinical symptoms and signs and the radiological findings on CT and MRI were documented. Albendazole was given preoperatively to patients with giant (>5 cm) or multiple cysts and postoperatively to all patients. The follow-up period ranged from 12 months to 22 years and the outcome was assessed using the Glasgow Outcome Scale (GOS). Findings. Sixty seven (95.7%) of our patients were children. Increased intracranial pressure and papilledema were the predominant findings in this group, whereas focal neurological deficits were most prevalent in adults. CT and MRI revealed round cystic lesions, isodense and iso-intense respectively to cerebrospinal fluid (CSF), with no rim enhancement or perifocal edema. Multiple cysts were identified in 3 cases. Extirpation of the cyst without rupture was accomplished in 56 patients (73.7%). Recurrences occurred in 19 patients (25%). 4 patients (5.3%) died within 6 months after surgery; 3 of these patients had multiple cysts and one died shortly after the operation due to anaphylactic shock following intra-operative rupture of the cyst. Conclusion. Long-term follow-up confirms that intracranial hydatid cysts should always be surgically removed without rupture; the outcome remains excellent in these cases. Correct preoperative diagnosis is vital for the successful outcome of surgery. A high index of suspicion is therefore required in endemic areas despite the availability of advanced neuro-imaging. Medical treatment with albendazole seems to be beneficial both pre- and post-operatively. Newer diagnostic methodologies, such as MR spectroscopy and MR diffusion weighted imaging, might lend themselves to the diagnosis of intracranial hydatid cysts.     

Complicated hydatid cysts of the lung: clinical and therapeutic issues

BACKGROUND: The clinical presentation and the preoperative and postoperative complications associated with pulmonary hydatid cysts depend on whether the cyst is intact or ruptured. The aim of this study was to review the problems encountered in treating ruptured pulmonary hydatid cysts and to highlight the risks associated with chemotherapy and the delay of surgical treatment in pulmonary hydatid disease. METHODS: The medical records for 67 patients of pulmonary hydatidosis were retrospectively investigated. The patients were divided into two groups based on whether the pulmonary cyst was intact (group 1, n = 34) or complicated (group 2, n = 33). A complicated cyst was defined as one that had ruptured into a bronchus or into the pleural cavity. All patients were treated surgically. Data related to symptoms, preoperative complications, surgical procedures performed, postoperative morbidity, hospitalization time, and cyst recurrence were collected from each individual's records, and the group findings were compared. RESULTS: In most cases of intact pulmonary hydatid cysts, the lesions were either incidental findings or the patient had presented with cough, dyspnea and chest pain. In addition to these symptoms, the patients with complicated cyst had presented with problems such as expectoration of cystic contents, repetitive hemoptysis, productive sputum, and fever. The differences between the groups with respect to the rates of preoperative complications and postoperative morbidity, frequency of decortication, and hospital stay were statistically significant (p < 0.05). CONCLUSIONS: Surgery is the primary mode of treatment for patients with pulmonary hydatid disease. Complicated cases have higher rates of preoperative and postoperative complications and require longer hospitalization time and more extensive surgical procedures than uncomplicated cases. This underlines the need for immediate surgery in any patient who is diagnosed with pulmonary hydatidosis.     

Surgical management of complicated hydatid cysts of the liver

AIM: To review the clinical presentation and surgical management of complicated hydatid cysts of the liver and to assess whether conservative surgery is adequate in the management of complicated hydatid cysts of liver.METHODS: The study was carried out at Sher-i-Kashmir Institute of Medical Science, Srinagar, Kashmir, India. Sixty nine patients with hydatid disease of the liver were surgically managed from April 2004 to October 2005 with a follow up period of three years. It included 27 men and 42 women with a median age of 35 years. An abdominal ultrasound, computed tomography and serology established diagnosis. Patients with jaundice and high suspicion of intrabiliary rupture were subjected to preoperative endoscopic retrograde cholangiography. Cysts with infection, rupture into the biliary tract and peritoneal cavity were categorized as complicated cysts. Eighteen patients (26%) had complicated cysts and formed the basis for this study.RESULTS: Common complications were infection (14%), intrabiliary rupture (9%) and intraperitoneal rupture (3%). All the patients with infected cysts presented with pain and fever. All the patients with intrabiliary rupture had jaundice, while only four with intrabiliary rupture had pain and only two had fever. Surgical procedures performed in complicated cysts were: infection-omentoplasty in three and external drainage in seven; intrabiliary rupture-omentoplasty in two and internal drainage in four patients. Two patients with intraperitoneal rupture underwent external drainage. There was no mortality. The postoperative morbidity was 50% in complicated cysts and 16% in uncomplicated cysts.CONCLUSION: Complicated hydatid cyst of the liver can be successfully managed surgically with good long term results.     

Multiple cystic pulmonary chondroid hamartomas colonized by <Emphasis Type="Italic">Aspergillus</Emphasis> species: Report of a case

Pulmonary hamartoma is the most common benign neoplasm of the lung, but the cystic form is very rare. This report presents the case of a 31-year-old woman with two cystic pulmonary lesions. She was radiologically and clinically diagnosed to have multiple ruptured hydatid cysts, and underwent a thoracotomy. The pathological investigation revealed that these lesions were cystic chondroid hamartomas, and one of the cysts was colonized by Aspergillus. Multilocular pulmonary cystic hamartomas are exceptionally rare and should be differentiated from other cystic pulmonary lesions. This is the first case of cystic pulmonary hamartomas colonized by Aspergillus species.
